Description

Technical Field

[0001] This utility model relates to the field of stud detection technology, specifically to a stud error detection device with a high detection rate. Background Technology

[0002] Studs are widely used as critical connectors in various industrial sectors, including machinery manufacturing, automobile assembly, and electronic equipment assembly. The integrity (whether any studs are missing) and quality (such as thread height and damage) of their installation directly affect the structural strength, sealing performance, and long-term reliability of the product. Therefore, accurate and efficient inspection of studs on workpieces at the end of the production line or after key processes is a crucial step in ensuring product quality. Currently, stud inspection mainly relies on manual visual inspection or equipment with limited automation, such as simple go / no-go gauges or fixed-position visual inspection.

[0003] There is an existing automated device for inspecting small parts on workpieces. This device typically includes a rotating indexing plate with multiple stations. Workpieces are transported to one station of the indexing plate by a feeding mechanism (such as a conveyor belt). The indexing plate rotates, sequentially sending the workpieces to a fixed vision inspection device for imaging. After inspection, the indexing plate continues to rotate, and the workpieces are sorted into different collection areas based on the inspection results. The core of this device is to achieve multi-station flow and inspection of workpieces through the rotating indexing plate.

[0004] However, the aforementioned existing technologies have significant shortcomings when applied to small features such as studs that require multi-angle, high-precision inspection. First, fixed-position visual inspection devices can usually only capture images from a single or limited angle, making it difficult to comprehensively cover the thread details of the stud (such as height and damage), which can easily lead to missed detections or misjudgments, affecting the detection rate. Second, their sorting mechanisms are usually simply designed, only able to achieve basic diversion, making it difficult to efficiently and reliably separate qualified and defective products in a compact space. Furthermore, the inspection and sorting actions rely on multi-step rotation positioning of the indexing plate, making the process less compact and limiting the improvement of overall inspection efficiency. These factors collectively restrict the realization of high-precision, high-efficiency stud error detection.

[0005] Based on this, this utility model designs a stud defect detection device with a high detection rate to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a stud error detection device with a high detection rate.

[0013] Furthermore, a first collection box and a second collection box are placed on the upper side of the main body of the device. The first collection box is located below the first discharge trough, and the second collection box is located below the second discharge trough.

The ring 8 serves as a workpiece bearing component and can rotate and move on the fixing disk 3. A deflection mechanism is connected between the ring 8 and the fixing disk 3 and is used to drive the ring 8 to perform precise angular deflection.

[0033] The outer side of the ring sleeve 8 is provided with four sets of symmetrically arranged connecting grooves 9, which serve as guide channels for the workpiece to enter. The inner side of the ring sleeve 8 is fixedly connected with symmetrically arranged partitions 10, which are used to separate the workpieces and form a detection station. The positions of the two sets of partitions 10 correspond to the connecting grooves 9, and the area between the two sets of partitions 10 forms a workpiece placement area, which provides a stable detection position for the workpiece.

[0034] The feeding mechanism is connected to the upper side of the main body 1 of the equipment and is responsible for orderly conveying the workpieces to be inspected to the inspection position. The upper side of the main body 1 of the equipment is fixedly connected to the upright plate 15, which serves as the support column of the inspection mechanism. The inspection mechanism is installed on the outside of the upright plate 15 and is used to perform all-round inspection of the studs on the workpieces. The lower side of the fixed plate 3 is provided with a first feeding groove 20 and a second feeding groove 21. The feeding groove is used to separate qualified products from unqualified products. The first feeding groove 20 and the second feeding groove 21 are respectively opened on the lower side of two sets of workpiece placement areas. The upper side of the fixed plate 3 is provided with a circular groove 24. The circular groove 24 provides installation space for the sealing mechanism and covers the first feeding groove 20.

[0037] A guide plate 11 is fixedly connected to the inner side of the connecting groove 9. The guide plate 11 is used to guide the workpiece to accurately enter the detection position. The guide plate 11 is close to the end of the conveyor belt of the conveying device 12 to ensure smooth transition of the workpiece.

[0038] The inspection mechanism includes a second motor 16, a second rotating shaft 17, a mounting plate 18, and an industrial camera 19. The second motor 16 is fixedly connected to the upper side of the upright plate 15 to provide rotational power for inspection.

The mounting plate 18 is fixedly connected to the bottom of the second rotating shaft 17 as a mounting platform for the industrial camera 19. The industrial camera 19 is fixedly connected to one side of the mounting plate 18 to collect detailed image information of the stud. The industrial camera 19 is matched with the workpiece placement area to ensure the accuracy and comprehensiveness of the inspection.

[0039] The main body 1 of the equipment has a first collection box 22 and a second collection box 23 placed on its upper side, which are used to collect qualified and unqualified workpieces respectively. The first collection box 22 is located below the first feeding trough 20, and the second collection box 23 is located below the second feeding trough 21, so as to realize automatic classification and collection.

[0040] The sealing mechanism includes a rotating rod 26 and a rotating disk 27. The rotating rod 26 is rotatably connected to the upper side of the fixed disk 3 as a power transmission component, and the end of the rotating rod 26 is located inside the circular groove 24. The rotating disk 27 is fixedly connected to the outside of the rotating rod 26 as an actuator to control the opening and closing of the feeding channel. The upper surface of the rotating disk 27 and the lower surface of the ring 8 are slidably connected and fit together to ensure smooth movement and good sealing. A fan-shaped hole 28 is opened on the outside of the rotating disk 27, and the fan-shaped hole 28 matches the first feeding groove 20. The opening and closing state of the feeding channel is controlled by rotation. A third motor 25 is fixedly connected to the bottom of the fixed disk 3 to provide power to the sealing mechanism, and the rotating rod 26 is fixedly connected to one side of the output shaft of the third motor 25 to ensure the reliability of power transmission.

[0041] The main body of the equipment 1 is externally fixedly connected to a terminal processor 29, which serves as the control center to coordinate the work of various components. The terminal processor 29 is equipped with an image processing algorithm program and a stud comparison model for image analysis and quality judgment. The terminal processor 29 is connected to the first motor 5, the conveying device 12, the second motor 16, the industrial camera 19, and the third motor 25 to realize intelligent control of the entire system.

[0042] In this embodiment, when the device is working, the workpieces with studs are placed sequentially on the conveyor belt of the conveyor device 12, and are separated and positioned by push plates 14 arranged at equal intervals. The conveyor device 12 is started, and the push plates 14 push the workpieces to move towards the ring 8. When the workpieces reach the end of the conveyor belt, they are guided by the guide plate 11 and accurately slide into the workpiece placement area formed by two sets of symmetrical partitions 10 inside the ring 8. Then the conveyor device 12 stops running.

[0043] At this time, the first motor 5, fixed in the mounting slot 4, is started, driving the first rotating shaft 6 to rotate, which in turn drives the connecting rod 7 fixed thereto to move. This causes the ring 8, which is fixed to the end of the connecting rod 7, to slide and deflect on the fixed plate 3, rotating and transporting the workpiece to the inspection station. After the first motor 5 stops, the second motor 16, installed on the upper side of the vertical plate 15, is started. The second motor 16 drives the second rotating shaft 17 to rotate, causing the mounting plate 18 fixed at its bottom and the industrial camera 19 on one side of the mounting plate 18 to move around the workpiece in a circular motion. The industrial camera 19 takes pictures of the studs on the workpiece from all directions, capturing details such as the thread height, integrity, and whether there is any damage.

[0044] The captured image data is transmitted to the terminal processor 29 in real time. The terminal processor 29 calls the built-in image processing algorithm program and stud comparison model to intelligently analyze and compare the stud features and accurately determine whether the stud installation on the workpiece meets the preset standard.

[0045] If the workpiece is determined to meet the standard, the terminal processor 29 issues a command to start the third motor 25. The third motor 25 drives the rotating rod 26 to rotate, which in turn drives the rotating disk 27 fixed on it to rotate, so that the fan-shaped hole 28 on the rotating disk 27 is aligned with the first feeding groove 20 on the lower side of the fixed disk 3. Then, the first motor 5 starts again, driving the ring sleeve 8 to continue rotating, pushing the qualified workpiece to the position of the first feeding groove 20. The workpiece falls through this groove into the first collection box 22 below it to complete the collection.

[0046] If the workpiece is determined to be non-compliant, the terminal processor 29 controls the third motor 25 to keep the rotating disk 27 in a misaligned state with the fan-shaped hole 28 and the first feeding groove 20, i.e., blocking the first feeding groove 20. When the first motor 5 drives the ring sleeve 8 to rotate, the qualified product channel is blocked, and the workpiece is continued to be transported to the position of the second feeding groove 21, and falls into the second collection box 23 below it through the groove. This process realizes the automatic identification, sorting and batch collection of workpieces that meet and do not meet the standards, which significantly improves the detection efficiency and sorting accuracy.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
